GEORGE MILLER STERNBERG, OF FORT RILEY, KANSAS.

Leners Patent No. 105,272, am@ July 12, 1870.

ELECTRO-MAGNETIC APPARATUS FOR REGULATING- VALVES AND DAMPERS.

The Schedule referred to in these Letters Patent and making part of the same.v

I, GEORGE MILLER STERNBERG, of Fort Riley, in the county of Davis, State of Kansas, have invented certain Improvemcntshin Machines for Regulating Dampers and Valves, of which the followingr is a speeitication.

These improvements have for their object the simplification ofthe mechanism described in Letters Patcnt No. 100,462, granted me March 1, 1870, by the substitution of a single train of wheels, moved by a weight, coiled spring, or otherwise, for the double clock-mechanism described in said Letters Pa'tent.

Also, a more perfect action of the spur-gears b b by detaehing them from the level' 11, and placing them eacll at the extremity of an independent lever, the opprste extremity of which is acted upon by the 1ever Also, the addition of the wheels f and g, which take the place of the windlasses d' d, the cord d, and

the wheel e, described in said Letters Patent No. 100,462.

Description of the Accompanying Drawing.

Figure lis a side elevatiomlwith the supporting` frame removed from the side shown.

Figure 2 is a plan view,

Like parts are lettered as in the drawing making part of the specification in Letters Patent N o. 100,462.

In the drawingl B is one of a'train of wheels, (the others not being drawn,) by which regular and continuous motion, obtained by means of a coiled spring, or otherwise, and

regulated by a ily-wheel, pendulum, or otherwise, is

transmitted to the wheels c c" by means of the small wheels i i', attached to their shaftc.

The spring h, acting upon the lever b, causes it to depress one extremity of the lever b, and to elevate its opposite extremity, together with the spur-gear b which it carries, thus separating the spur-gear b from its connection with the wheels dd, and allowing them to revolve independently of each other.

At the same time, the spur-gear b is allowed, by its own weight, assisted, when necessary, by a slight spring, to fall upon and engage the wheels c' d', causing the wheel d', which is loose upon the shaft c, to revolve in unison with the wheel c the same as if it were fast to the shaft. l v l The small wheel l' is fast to the wheel d', (as is likewise the wheel d to 11,) and serves to communicate the motion ot' the wheel d', when it is in gear with c', to the wheels g andj.

The wheel g is interposed between ll' and f, for the purpose of causing f to revolve in the same direction with ll.

The shaft of the wheel j' passes through the framework O, and may be made the shaft of the valve it is desired to regulate, or it may be made to transmit its l motion to such valve or damper by means of a cord or band passing'around a pulley attached to its shaft, or otherwise.

When the wheel B is in motion, through the wheels i', c', al', d, and g upon one side, and the wheels i, c", d, and cl. on the other, the wheel f is eansedto move continuously, either to the right or to the left, accordying as the spur-gear b engages the wheels c' d', or the spur-gear b engages the wheels c (l.

The lever b, by which the spur-wheels b b are thrown in and out of gear, is operated by the spring hkon one side, and a lever, c'. not here shown, upon the other.

The operation of the lever a, carrying an armature, a", is fully explained in Letters Patent No. 100,462. l

Having thus described. my invention,

What I claim as new, and desire to secure by Letf ters Patent, is

The single system of-trainwork, in combination with the wheels g, f, d, and d, the levers b, and the lever b, operating in the manner and for the purpose substantially as described.
